Don't use the auxillary circuit to wire your solenoid, its always on
I showed in here how I used an add a circuit to wire the battery isolator solenoid, and I had wired it to my auxiliary power circuit in the fuse box underneath my hood. This was a mistake, all of the small fuses in the fuse box under the hood of an F150 half ton are hot whether or not the ignition is switched on. Luckily I figured this out before I went and stranded myself (its always good to check your stuff with real application). Like I said, I'm definitely no pro and pieced all this together from reading forum posts and watching you-tube videos.
I rewired the add a circuit to the ignition fuse under the dash of my truck, now the solenoid only closes when the ignition is turned on and it breaks the circuit when I turn the truck off and remove the key. This way my camper battery bank is truly isolated from the truck starting battery when the truck is off, guaranteeing I will not kill my truck battery with camper accessories. Only took a few minutes, I just wanted to clarify on here so I don't lead anybody else in the wrong direction. My apologies for any confusion.
